This from correspondent Dan Rea. Thought it was worth posting on its own, rather than having it buried in a comment thread. Dan’s comments follow the vid.
If you’d like to cut to the creationism-bashing you can skip to the 31:00 mark, but the whole video is interesting and (as always with deGrasse) very entertaining. The overriding point he is making is intriguing; he points out how many of the greatest minds throughout history subscribed to creationist ideas at the limits of their understanding, and how these limits shift over time. In the past I’ve heard him describe the concept of god as an ever shrinking archetype as humanity’s knowledge increases, but I never really thought about the processes going on in the minds of great people (far smarter than me) who came to creationist conclusions.
